In most industrialized economies inflation tends to be pro-cyclical; that is, inflation is high during times of high economic activity. When economic activity is measured by the unemployment rate this statistical relationship is known as the Phillips curve.

This article surveys recent advancements in the theory of optimal monetary policy in models with a New Keynesian Phillips curve. It identifies four policy implications. First, near price stability is optimal. Second, simple interest rate feedback rules that respond aggressively to price...

We review single-equation methods for estimating the hybrid New Keynesian Phillips curve (NKPC) and then apply those methods to U.S. quarterly data for 1955?2007. Estimating the hybrid NKPC by the generalized method of moments yields stable coefficients with a large role for expected future...

This paper surveys estimates of New Keynesian Phillips curve (NKPC) parameters that have been obtained by fitting fully specified dynamic stochastic general equilibrium (DSGE) models to U.S. data. We examine various sources of identification in the context of a simple analytical model. DSGE...

Several arguments are relevant. (1) In the absence of the zero lower bound (ZLB), the optimal steady-state inflation rate, according to standard reasoning, lies between deflation at the steady-state real interest rate and the Calvo-model value of zero, with calibration indicating a larger weight...

In linear macroeconomic models, an active Taylor rule for monetary policy can guarantee a locally unique nonexplosive equilibrium. In a series of articles, Benhabib, Schmitt-Grohé, and Uribe looked beyond the local dynamics and showed that active Taylor rules could interact with the zero bound...

K-core inflation is a new class of underlying inflation measures. The two most popular measures of underlying inflation are core inflation and trimmed mean inflation. The former removes fixed categories of goods and services (food and energy) from the inflation calculation, and the latter...
